GRAIN-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 298,302, dated May6,1884.

Application filed February 8, 1833.

To all whom, t may concern:

Be it known that we, EDWARD HUBER and FREDERICK STRORRL, of Marion,inthe county of Marion, and in the State of Ohio, have invented certainnew and useful Improvements in Thrashing-llIachincs; and we do herebydeclare that the following is a full, clear, and eX- act descriptionthereof, reference being had to the accompanying drawings, and to theletters of reference marked thereon, making a part of this specication.

Our invention relates to certain improvements in grain-separators; andit consists of the construction and arrangement of parts whereby a moreperfect separation of the grain from the chaff than heretofore isobtained, the operation and advantages of the same being hereinaftermore fully set forth, and pointed out in the claim.

In the accompanying drawings, Figure 1 represents a longitudinalvertical section through the machine, showing the improvements thereto;and Eig. 2, a plan view of the vibrating' separator.

A represents the body or frame of the thrasher, which may be of anyapproved construction. In this frame are located various working partsof the machine, described here- Lio inafter. Near' the upper part ofthis frame are located the inclined vibrating straw-carriers E2 and E3,supported at their contiguous ends by the lever D, which is fulcrumed atE. The other end of each carrier is supported by the swinginglink C. Thebottom of each carrier is formed of inclined slats so placed that as thestraw'is carried backward the grain will fall between the slats, theoscillatory motion of the said carriers causing the motion of the strawand grain, as will be readily understood.

' back. It extends from under the drum to a grain-carrier, will be morefully hereinafter set forth.

The carrier K is supported Iby the swinging links M, and is connected tothe lever D by means of the rods S and s,which are connected by the linkT. These connections serve to give the vibratory motion to the carrierK.

To the upper portion of the rear of the said carrier K is hinged theslatted riddle N, having at its rear end a series of pins, I. The riddleis also supported near its rear end by a link or links, which may bepivoted or flexible, as preferred, and serve to regulate the throw ofthe same. Under the rear of the riddle N and carrierK is the shoe R,contain- 4ing the sieve R.

It is evident that as the grain and straw are caught and thrownrearwa'rd from the thrashing-drum they will fall upon the vibratingcarrier E3 and be slowly carried toward the rear of the machine, thelight chaff being by the force of the blast carried entirely through thesaid machine. As the straw is conducted over the carriers, the grain isby the constant motion shaken from the said straw and falls through theintervening space to the secondary carrier K, the grain that is carriedover to the straw-carrier E2 by traveling down the inclined tablelocated under the said carrier (shown in Fig. l) also falling on thegraincarrier before mentioned. A considerable portion of the chaff willaccompany the grain, and al portion will be blown out from the machinebelow the inclined table. The thoroughly-cleaned grainbeingproportionally very heavy, will readily fall through the inclined slatson the grain-carrier K onto the solid bottom below, while the blastwhich passes over the slats, and also under and up through them, willcarry all the imperfectly- IOO thrashcd heads and remaining chaif to therear, while any thrashed grain which has been carried to the riddle willreadily fall through the slats to the sieve below. Theimperfectlythrashed heads are carried rearward to the fingers P, betweenwhich they easily fall to the shoe R below, and are from there carriedthrough the usual mechanism to the thrashing-drum. Any straw or chai'that may have reached the iingers P is by the blast carried beyond theshoe as they fall, and so out of the machine. The grain is carried onthe solid bottom of the carrier K to the rear till it falls on thescreen R', and is from thence delivered in a clean condition to theproper outlet of the machine. The upward throw of the riddle N, beingconsiderably greater than that of the carrier K, somewhat retards therearward movement of the material, but overcomes, in connection with theblast, the force of gravity exerted on the imperfectly-thrashed heads,and so carries them rapidly backward till they reach the iingers P, andthe latter work through the mass to the screen R.

The forward extension of the grain-carrier K is for the purpose ofcatching the thrashed grain that falls before reaching the straw-carrierE3. It is not necessary to have this portion slatted, as nothing butclean-thrashed grain can fall at this point.

Having thus described our invention, what we claim is- As an improvementin grain-separators, the combination, with the shakers E2 and E3 andtheir connections, of the grain-carrier K, having a slatted orperforated top, the swinging links M, supporting said carrier, theriddle N, provided with ngers P and hinged to the rear of said top, andthe suspensory links supporting the rear end of said riddle, so as togive it vibratory motion relative to the graincarrier, substantially asand for the purpose set forth.

In testimony whereof we aiix our signatures,

in presence of two witnesses, this 13th day of 45 December, 1882.
